Ahh, thanks, that's what I was looking for...but it doesn't remove the
installed kernel headers.

$ dpkg -l | grep linux-image
linux-image-2.6.15-23-686
linux-image-2.6.15-26-686
linux-image-686

What confuses me is 'linux-image-686'.  I'm guessing that's some kind of
meta package that I should just leave alone.

Meta packages confuse me in general.  When should I install them or remove
them?

Thanks.
